  Next, the address setting device 400 of this embodiment will be described. FIG. 9 is a schematic diagram showing the connector-attached harness 2 in which an address is set to each connector 3 by the address setting device, and FIG. 10 is a schematic diagram showing a schematic configuration of the address setting device 400. The assembly 4A in which the plurality of connectors 3 and the ECU connector 5 are assembled to the harness 4 and the address is not set and the harness 2 with the connector after address setting are the same except for the presence or absence of the set address. , Shown in the same figure. Moreover, in FIG. 9 and FIG. 10, the example which set the number of the connectors 3 of the harness 2 with a connector to four is shown.

  In the assembly 2A, which is a harness with a connector before address setting shown in FIG. 9, the connector 3 is a common product, and an individual address is not yet stored in the internal address storage unit 306 (whether there is no stored content). Or a common value is stored), and since no address is set, it cannot be distinguished. When an individual address is set in the address storage unit 306 of each connector 3 of the assembly 2A, the harness 2 with connector capable of performing multiplex communication is obtained.

  As shown in FIG. 10, the address setting device 400 is configured so that all the connectors 3 and the ECU connector 5 of the assembly 2A to be the harness 2 with a connector can be mounted. In addition to being electrically connected to the harness 4 via the connector 5, it is also electrically connected to the encoder position detection signal input terminal (position detection signal receiving terminal) 92 of each actuator connector 3. Here, the position detection signal input terminal 92 to which the address setting device 400 is electrically connected includes at least one of the terminals 92a and 92b among the position detection signal input terminals 92 shown in FIG.

  The address setting device 400 communicates with the motor control unit 300 of the connector 3 through the bus line 100 of the harness 4 of the connector-equipped harness 2 and transmits and receives instructions, and controls the operation of each component of the address setting device 400. A control unit 420 including a processing circuit or a microcomputer to perform, a storage device 430 including a RAM and a ROM for storing a program for address setting, and an address identification signal connected to a position detection signal input terminal 92 of each connector 3 Input / output unit 440, power supply device 450 for supplying power to each component, trigger switch 460 for starting the operation program of address setting device 400, and display device 470 for notifying completion of address setting. .

  The input / output units 440 transmit individual address identification signals simultaneously to the position detection signal input terminals 92 of the respective connectors 3. When the address setting device 400 completes address setting for each connector 3 of the assembly 2A, the assembly 2A becomes the harness 2 with connector capable of performing multiplex communication.

  Next, an address setting operation performed by the address setting device 400 based on the above configuration will be described. FIG. 11 is a flowchart showing the address setting control operation of the control unit 420 of the address setting device 400 and the address writing control operation performed by the control unit 305 of the motor control unit 300 in the connector 3 in response to this.

  As shown in FIG. 11, when the assembly 2A is connected to the address setting device 400 and the trigger switch 460 is pressed, the control unit 420 starts operation according to the address setting program.

  First, the control unit 420 causes the communication unit 410 to transmit an “address transmission flag signal” that notifies the motor control unit 300 of each connector 3 that the address is being set from the ECU connector 5 via the bus line 100 ( Step 501). Next, an address identification signal having an individual address value waveform (in this example, the number of pulse waves corresponding to the address value) is input to the input / output unit 440 with respect to the position detection signal input terminal 92 of each connector 3. Transmit (step 502).

  Here, the address identification signal is not limited to a signal having a different number of voltage pulses, and any signal having a different voltage pulse pattern may be used.

  When the control unit 305 of the motor control unit 300 of each connector 3 receives the “address transmission flag signal” via the bus line 100 (step 601), it waits for an address identification signal to the position detection signal input terminal 92 (step 602). The address identification signal is received (step 603).

  When the control unit 420 of the address setting device 400 executes Step 502 and finishes transmitting the address identification signal from the input / output unit 440 (Step 503), each motor control unit 300 is communicated from the communication unit 410 via the bus line 100. The transmission of the “address transmission flag signal” sent to is stopped (step 504).

  The control unit 305 of the motor control unit 300 continues executing steps 602 and 603 until it detects the end of reception of the “address transmission flag signal” (step 604). When the transmission stop of the “address transmission flag signal” 504 is received, the received address identification signal is held (step 605).

  The control unit 420 of the address setting device 400 that has stopped transmitting the “address transmission flag signal” in step 504 transmits the “address write flag signal” to the motor control unit 300 from the communication unit 410 via the bus line 100 ( Step 505). Receiving this signal, the motor control unit 300 writes and stores the address value recognized and held in the address storage unit 306 (step 606).

  Then, the control unit 420 of the address setting device 400 displays on the display device 470 that the address setting has been completed and notifies the operator or the like (step 506). Through the above operation, the plurality of connectors 3 incorporating the motor control unit 300 and the ECU connector 5 are assembled to the harness 4 including the bus line 100, and the assembly 2A in which no address is set is stored in the address storage unit 306. In addition, the connector-equipped harness 2 in which individual addresses are set in the respective address storage units 306 of the respective connectors 3 can be obtained.

  Here, the control unit 420 and the communication unit 410 of the address setting device 400 correspond to address setting instruction means for transmitting an address setting instruction from the ECU-side connector 5 to the plurality of motor control units 300 via the bus line 100, and address The control unit 420 and the input / output unit 440 of the setting device 400 correspond to an address signal transmission unit that transmits an individual address signal to the motor connection terminal 9 of each motor control unit 300 in synchronization with transmission of an address setting instruction.

  Further, a process of forming the assembly 2A in which the plurality of connectors 3 and the ECU connector 5 are assembled to the harness 4 shown in FIG. 9 and the address is not set is an assembly forming process, and the address setting shown in FIG. The process of setting individual addresses for each connector 3 in the apparatus 400 is an address setting process.

  According to the above-described configuration and operation, address setting instructions are transmitted from the ECU-side connector 5 to the plurality of motor control units 300 via the bus line 100, and the position detection signals of the respective motor control units 300 are synchronized with this. An individual address signal can be transmitted to the input terminal 92 to set an individual address in the address storage unit 306 of each motor control unit 300 of the plurality of actuator connectors 3. Therefore, the address signal can be identified using an internal circuit connected to the position detection signal input terminal 92, and a plurality of address signals are transmitted to the position detection signal input terminals 92 of the plurality of motor control units 300, respectively. The address can be simultaneously set in the address storage unit 306 of the motor control unit 300. In this way, the internal circuit of the actuator connector 3 can be prevented from becoming complicated, and the address setting man-hour can be reduced.

  The individual address signal is input to a position detection signal input terminal 92 for receiving a rotation operation position detection signal of a door servo motor to be connected among the motor connection terminals 9 of each motor control unit 300. Therefore, since the address signal can be identified using the position detection circuit connected to the position detection signal input terminal 92, it is possible to reliably prevent the internal circuit from becoming complicated as compared with the case where the address signal is input to the drive power output terminal 91. can do.

  In addition, since the actuator connector 3 incorporating the circuit of the motor control unit 300 can be made common to one type, it is possible to eliminate management man-hours for each address type, improve manufacturing efficiency, and reduce the connector inventory. It is possible.

  In addition, each connector 3 only needs to have an address storage unit 306 composed of a small storage memory capable of storing addresses, and the additional circuit scale can be reduced as compared with a method of providing a fixed address value. An increase in physique can also be suppressed. Further, it is not necessary to add an address setting function to the master ECU 200 for the air conditioner.

(Second Embodiment)
Next, a second embodiment will be described based on FIG. 12 and FIG.

  Compared with the first embodiment, the second embodiment has a function of checking whether or not the address setting device can output drive power from the drive power output terminal of each actuator connector. Is different. In addition, about the part similar to 1st Embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  As shown in FIG. 12, in the present embodiment, the address setting device 400A has a connection portion with the drive power output terminal 91 of each connector 3, and this connection portion uses the door servo motors 110, 120, 130, A pseudo load resistor 480 having an electric resistance value equivalent to 140 or 150 is electrically connected. A potentiometer 490 that detects the voltage across the pseudo load resistor 480 is provided, and the voltage across the pseudo load resistor 480 detected by the potentiometer 490 is input to the control unit 420 via the input / output unit 440. It has become.

  Here, the configuration including the pseudo load resistor 480 and the potentiometer 490 is connected to the driving power output terminal 91 for outputting the driving power to the door servomotor among the motor connection terminals 9 of the respective motor control units 300 and is driven. This corresponds to output state detection means for detecting the output state of power.

  As shown in FIG. 13, the control unit 420 of the address setting device 400A of the present embodiment transmits an “address write flag signal” from the communication unit 410 to the motor control unit 300 via the bus line 100 in step 505. When the motor control unit 300 receiving the signal writes and stores the address value recognized and held in step 606 in the address storage unit 306, the address “address: 1” is transmitted from the communication unit 410 via the bus line 100. A servo motor drive instruction signal is transmitted to the addressed connector 3 (step 507).

  The motor control unit 300 of the connector 3 at address 1 that has received the signal via the bus line 100 (steps 607 and 608) energizes the drive power output terminal 91 to operate the door servo motor (step 609). .

  The address setting device 400A applies the energization current to the pseudo load resistor 480, detects the energization with the potentiometer 490, and confirms that the pseudo load resistor 480 at the connection position corresponding to the address: 1 is correctly energized ( Step 508). When it is confirmed that the power is correctly supplied, the control unit 420 of the address setting device 400 transmits a servo motor drive stop instruction signal (step 509), and the control unit 305 of the motor control unit 300 transmits to the drive power output terminal 91. Is stopped (step 610).

  Similarly, the control unit 420 of the address setting device 400 transmits the servo motor drive instruction signal of each address from the communication unit 410 via the bus line 100 and the pseudo load resistor 480 at the corresponding address position after the address: 2. It is confirmed that the energization is performed (step 510).

  Then, the control unit 420 confirms the energization state of the pseudo load resistor 480 at all addresses (step 511), and when energization to the pseudo load resistor 480 is correctly performed at all addresses (YES in step 512). In the case), the display device 470 displays that the address confirmation is completed (step 506). If energization to the pseudo load resistor 480 is not correctly performed at any address (NO in step 512), the address value where the error has occurred and the fact that the error has occurred are displayed on the display device 470 ( Step 513), the operator is notified of the failure and the defective address.

  According to the above-described configuration and operation, in addition to the same effects as those of the first embodiment, after setting individual addresses in the respective address storage units 306 of the plurality of actuator connectors 3, Via the bus line 100, a motor drive instruction signal is transmitted together with an address to a plurality of motor control units 300, and the output state of the drive power from the drive power output terminal 91 of the motor control unit 300 set with the corresponding address is confirmed. be able to.

  According to this, it is possible to inspect whether or not the plurality of motor control units 300 can drive and control the door servo motors connected to the respective actuator connectors 3 by the address setting device 400A.

  As described above, the address setting device 400A has a function as an address checking device in addition to an address setting function, and an operation confirmation function for confirming that the motor control unit 300 of the connector 3 can normally energize the motor. Yes. Therefore, if the harness 2 with a connector is connected to the address setting device 400A, since the address setting to the inspection and the operation confirmation can be performed, man-hours can be reduced as compared with the case where the inspection and the operation confirmation are individually performed. In addition, if there is an abnormality in the address setting operation, it can be detected immediately and repaired or handled, so that it is possible to prevent a large number of defective products from occurring.

  In this embodiment, the function inspection after address setting is sequentially performed for each address. However, when the drive voltage value is different for each address or when it is not necessary to check the set address, the function inspection is performed. Are not performed sequentially for each address, but may be performed simultaneously.

(Third embodiment)
Next, a third embodiment will be described with reference to FIGS.

  The third embodiment is different from the first embodiment in that the door servo motor position detection method is a potentiometer method. In addition, about the part similar to 1st Embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  As shown in FIG. 14, in this embodiment, each door servo motor 110, 120, 130, 140, 150 (only the door servo 110 is shown in FIG. 14), which is an actuator connected to the actuator connector 3, is a rotational position detecting means. The potentiometer 1150B that changes the resistance according to the rotational position is provided.

  Correspondingly, the detection circuit unit 304 of the motor control unit 300 incorporated in the connector 3 in this embodiment is positioned based on the change in voltage value due to the resistance change of the potentiometer 1150B of the connected door servo motor. Detection is to be performed.

  Therefore, the address identification of the motor control unit 300 of each actuator connector 3 at the time of address setting is made to recognize the difference in address by changing the voltage value applied to the potentiometer connection terminal.

  FIG. 15 is a schematic diagram showing a schematic configuration of the address setting device 400B. The block configuration of the address setting device 400B is the same as that of the address setting device 400 of the first embodiment, but the input / output unit 440B is a position detection signal input terminal 92 that is a voltage detection terminal of the potentiometer connection portion of each connector 3. It is designed to be connected to two terminals. Then, when executing step 502 shown in FIG. 11, an address identification signal having a different voltage value is inputted to the position detection signal input terminal 92 of each connector 3.

  FIG. 16 shows an example in which the address value is identified based on the difference in the applied voltage value. The voltage applied to the position detection signal input terminal 92 of each connector 3 from the input / output unit 440B of the address setting device 400B. Adopts a method of recognizing an address value by inputting an address signal that differs by 0.5V.

  For example, address 1 is recognized when the applied voltage is 0.5 V, address 2 is recognized when the voltage is 1.0 V, address 3 is recognized when the voltage is 1.5 V, and address 4 is recognized when the voltage is 2.0 V. If a program is adopted and individual voltages are applied to the four connectors 3, four types of addresses can be set respectively.

  In order to enable stable address setting even if there is a slight variation in the applied voltage value, as shown in FIG. 16, the same address value is set as long as it is within a predetermined applied voltage range under the condition that the address values do not overlap each other. It is supposed to be set.

  According to the above-described configuration and operation, even if the rotational position detection means of each door servo motor is a potentiometer type, the same effect as that of the first embodiment can be obtained.

Is set equal to FIG. 17 shows an example in which the number of connectors 3 of the harness 2 with connectors is four.

  That is, as shown in FIG. 17, the ECU connector 5 of the harness with connector 2 is connected to the connection portion 411, and the actuator connector 3 (connectors 310, 320, 330, 340) is connected to the connection portions 441 to 444, respectively. Address setting is performed.

  In the connector mounting design dimension of the harness 2 with connector 2 to the harness 4, for example, when the distance between the connector 5 and the connector 310 is a, the distance between the connection portion 411 and the connection portion 441 is also a. Similarly, when the distance between the connector 310 and the connector 320 is b, the distance between the connection part 441 and the connection part 442 is also b, and when the distance between the connector 320 and the connector 330 is c, the connection part 442. The distance between the connector 443 and the connector 443 is c, and when the distance between the connector 330 and the connector 340 is d, the distance between the connector 443 and the connector 444 is also d.

  According to this, when the connector interval of the harness 2 with the connector is not made according to the specified interval dimension and there is a portion where the interval is short, a connector that cannot be connected to the connection part of the address setting device 400 occurs, It is possible to easily find a defect whose interval dimension is shorter than a regular regular interval dimension.

  In addition, when there is a portion where the connector interval of the harness 2 with connector is longer than a predetermined interval dimension, sagging occurs in the harness 4 when each connector is connected to the connection portion of the address setting device 400. In addition, it is possible to easily find a defect in which the distance dimension is longer than the specified normal distance dimension.

  In this way, it is easy to confirm that the plurality of actuator connectors 3 and the ECU connectors 5 are arranged at predetermined intervals with respect to the harness 4, and the addresses of the plurality of actuator connectors 3 are addressed. It is also possible to prevent erroneous settings.

  In addition, it is preferable to set the mutual space | interval of each connection part 411,441-444 of the address installation apparatus 400 to the center value of the connector attachment space | interval design dimension of the harness 2 with a connector, or the short dimension permitted on design. According to this, the dimension abnormality goods of the harness 2 with a connector can be detected easily.
